The SbVec4s class is a 4 dimensional vector with short integer coordinates.
This vector class provides storage for a 3 dimensional homogeneoues vector (with the 4 components usually referred to as <x, y, z, w>) aswell as simple integer precision arithmetic operations.
|
inline |
The default constructor does nothing. The vector coordinates will be uninitialized until a call the setValue().
Referenced by dot(), operator*=(), operator+=(), operator-(), operator-=(), operator/=(), operator/=(), setValue(), setValue(), and setValue().
